摘要：

A new determination of the upper limit to the cosmic diffuse background radiation, at similar to 110 nm, of 300 photons s(-1) cm(-2) sr(-1) nm(-1) is placed in the context of diffuse background measurements across the entire electromagnetic spectrum, including new optical, infrared, visible, and gamma-ray background measurements. The possibility that observed excess diffuse visible radiation is due to redshifted cosmological Ly alpha recombination radiation is explored. Also, a new standard of units for the display of spectra is advocated.
